Description

Your software is too slow, and you need to figure out why. It’s natural to reach for the cProfile profiler that’s built-in to Python, but as a deterministic profiler it suffers from a number of limitations.

In this talk you’ll learn about better tools for performance optimization:

• Sampling profilers, which distort the results less and give you a calltree overview of your running application.
• Trace-based logging, which can help you figure out not only which functions are slow, but also which particular inputs are causing the slowness.
